Title: Electric wave-signal-collecting systems
IPC: H01Q5/00
Filed: 1936-05-13
Abstract: 462,872. Wireless receiving - apparatus. HAZELTINE CORPORATION. May 13, 1936, No. 13542. Convention date, June 10, 1935. [Classes 40 (iii) and 40 (v)] The invention comprises improvements in matching and coupling an antenna to a wireless receiver when a two wire transmission line is employed. Fig. 2 shows a dipole aerial 10a, 10b coupled by a filter 11a, 11b to a line 12a, 12b which is coupled to the receiver 14 by a filter 13a, 13b. The aerial, as shown in Fig. 1, preferably comprises a doublet made up of two pairs of oppositely extending conductors diverging from a common centre and the line, a pair of spaced wires separated at intervals by transposition blocks or a pair of twisted insulated wires. When operating on a lowfrequency band, the aerial may be independentlv earthed or, as shown, be earthed over the line by the connection of the mid-point of inductance 64 to the junction of inductances 52a, 52b. Variation in impedance of the line as a ground connection, when the line is long, is reduced by terminating the line in a resistance 74 equal to its' image impedance relative to ground. The filters 11a, 11b, 13a, 13b form the subject-matter of Specifications 462,873 and 462,874 and are so interconnected as to cover contiguous wavebands. On the shortwave band, the aerial operates as a balanced doublet and the filter 11a, couples the balanced aerial currents to the line 12a, 12b as balanced or circulating currents and matches the impedance of the aerial to that of the line. The line on this waveband is coupled and matched to the receiver by filter 13a. On the longer waveband the aerial operates as a simple flat top aerial and the unbalanced currents are transferred as balanced currents to the line by filter 11b and from the line to the receiver by filter 13b. The Specification gives numerical data for a system operating from 155 to 18 megacycles.

Thus the hot gases from the fire, when it is burning downwardly, can pass directly up the flue 5 to the underside of the hot-plate without losing heat to the boiler or oven. In the form shown, the hot gases after passing across the top of the oven return in a parallel fine beneath the hot-plate to the chimney flue 14. For heating the oven and the boiler, an auxiliary flue 23 and a flue 20 are provided. A direct outlet 17 to the chimney flue, beside the flue 14, is provided. Dampers 15, 25, 21, 17a control the duct 5, the flues 23, 20, and the outlet 17, respectively. The dampers may be thermostatically controlled. The dampers 15, 25 may be synchronized to open constantly in the same ratio while in addition the damper 25 may be separately movable. The front wall 6a of the boiler 6 is insulated, and the nose 3 of the plate 4 may be of chrome alloy. In another form, the hot gases after passing across the top of the oven pass down the far side of the oven to the chimney flue. To prevent radiation from the fire during hot weather a screen, e.g. of one or more layers of wire gauze, expanded metal, or metal mesh may be used to mask the fire opening while passing sufficient air for combustion. Specification 455,519 is referred to.

Title: Improvements in or relating to blast propulsion
IPC: F02K7/00
Filed: 1944-07-18
Abstract: 583,549. Generating combustion products under pressure. ROY, R. DE. July 18, 1944, No. 13757. [Class 51 (i)] [Also in Group XXVI] A blast propulsion unit comprises one or more combustion chambers 12 to which fuel and air are supplied under pressure and a discharge nozzle 28 surrounded by an annular gas conduit 31 communicating with the combustion chamber and adapted to act as an ejector to assist in scavenging the combustion chamber and in introducing air for combustion therein. Air under pressure from a collector 17 enters the chamber 12 through apertures 18 controlled by a valve 19, to be consumed by a rich fuel-air mixture, is injected past a valve 48, when an igniter 16 fires the charge. The explosion opens an exhaust valve 24 covering outlet ports 23 leading to the discharge nozzle 28 and movement of the valve causes a disc 26 secured to its spindle 25 to engage an abutment 21 on the stem of the inlet valve 19 after the exhaust valve 24 has opened a predetermined distance. The air thus admitted first scavenges and then charges the chamber 12. Rigid with the air valve 19 is an annular valve 32 controlling the annular gas conduit 31 and permitting the scavenging air to escape along the gas conduit to exert an ejector action on the nozzle 28. A spring 27 between the disc 26 and chamber wall 13 closes the exhaust valve 24, and claws 46 on the disc engage the abutment 21 to close the inlet valve 19. To prevent the exhaust valve from opening before a predetermined pressure has been reached, spring-pressed pawls 47 resist movement of the disc 26. The spindle 25 also carries a conical member 55 adapted to actuate the fuel inlet valve 48 through a rod and lever linkage. In another form.described in the provisional specification the exhaust valve through its spindle actuates a fuel pump, the claws 46 and pawls 47 are omitted and a separate spring closes the inlet valve.

Title: Improvements in or relating to liquid sampling for gas chromatography
Inventor: JENKINS PHILIP
IPC: G01N30/12
Filed: 1960-04-21
Abstract: A liquid sample is introduced into a stream of carrier gas for passage to a gas chromatograph column by filling a micro-pipette 15 or 42 with the liquid, placing the pipette in a bore 11 or 40 of a rotatable valve body 10 or 34, discharging the pipette so that the residue of liquid on the walls forms the sample and rotating the valve body so that the pipette and sample are brought into contact with the carrier stream.  As shown in Fig. 2, the filled pipette is fitted in a holder 16 having a springy slotted end and the holder is screwed into the <PICT:0906121/III/1> <PICT:0906121/III/2> bore 11. The pipette is then discharged by holding against it an absorbent wad 28 pressed out from a holder 26 by a pusher member 29 and is pushed back into the holder by extra pressure on the holder 26.  Finally the valve body 10 is rotated through 90 degrees so that the bore 11 connects the gas conduits 8, 33.  In Fig. 8, the valve body 34 is rotatable on pins 38 on an axis parallel to the conduits 35, 36 or oblique to them so that the bore 40 slopes downwards, and the pipette 42 is retained in position by a spring-loaded pin 43.  When the valve body is in the loading position, the carrier gas stream is maintained through a bore 12 passing behind the bore 11 or through a bore 41 which may be of horseshoe section to reduce the time of interruption of the stream during rotation of the valve body.  Heat may be applied to the sample, either directly or by preheating the carrier gas by means of a coil 44.
